You need software that solves a real problem, built right the first time, by someone who understands your business and not just your stack. "I am a former CIO and CTO and have worked with hundreds of software engineers. Orest is one of the best in terms of raw talent, knowledge, efficiency, creativity, flexibility, communication and working relationship. I could not recommend him more highly." — client review, February 2026 I'm Orest — a full stack developer and founder of SoftDoes, a Kansas City-based team. I architect and lead every build personally; my team gives you agency capacity without agency overhead. Upwork wrote a feature on how we did it. What clients hire me for: • Web applications and SaaS platforms — React, Next.js, Node.js, TypeScript, Python, PostgreSQL and Supabase, with Stripe subscriptions, marketplaces and multi-tenant architecture • AI development — AI agents, chatbots and voice agents, LLM integration with OpenAI and Claude, RAG pipelines, and automation built into real workflows • Taking AI-built prototypes to production — your app started in Lovable, Bolt or Claude Code and now needs auth, security, payments and real infrastructure • API development and integration — REST and GraphQL, third-party integrations, webhooks, payment gateways, CRM and business system connections • Websites and e-commerce — WordPress, WooCommerce, Shopify, Webflow and custom builds, redesigns, migrations and performance work • Mobile apps — React Native for iOS and Android • Cloud and DevOps — AWS, GCP, Azure, Docker, CI/CD, and compliance-ready builds for healthcare (HIPAA) and fintech (PCI) Recent results: • A healthcare founder went from concept to a live, compliant product in under six weeks • A construction company replaced five fragmented tools with one custom operations platform • A fintech team cut onboarding time in half with an AI-assisted workflow built in a single sprint "Orest, Nazarii, and their team built our full AI-powered SaaS platform from scratch. Communicative and reliable, consistently delivering quality work on schedule. Already starting our next project together." — Will S., AI SMS platform, February 2026 I work best with companies big enough to need real software and clear-eyed enough to know that building it wrong the first time costs more than doing it right.
